.To all whom it may concern.-

Be it known that we, GEORGE W. LAMB, of Oumminsville, and BENJAMIN G. VAN DYKE, of Ivanhoe, both in the county of Hamilton and State of Ohio, citizens of the United States, have invented certain new and useful Improvements in Railway-Oars; and we do hereby declare the following to be a full, clear, and exact description of the invention,

. such as will enable others skilled in the art also, in means providing for a central and uniform displacement of the weight of the car-body upon the tru ck-framing and freedom of lateral motion of the truck under the carbody; also, in means furnishing an elastic or yielding connection between the car-bod y and the truck-frame.

Figure 1 shows a detail of construction of a roller device. Fig. 2 is a side View of a cartruck and a portion of a car-body framing connected thereto, certain parts of the truck being in section along the plane 00 w, Fig. 3, and the safety-beams 0 being omitted. Fig. 3 is a top view of a truck having our improvements. Fig. 4 is a mid-sectional view of the end parts of a car-truck and car-body along the plane y y, Figs. 2, 3, and 5. Fig. 5 is a top view of the end parts of a car-truck and oar-body, partly in section,along the plane y y, Fig. l. Fig. 6 is a bottom View of one end of a car-body having our improvements. Fig. 7 shows a detail of construction.

Letters are used to indicate ordinary parts of a truck and a car-body. Numbers are used to indicate parts comprised in our improvements.

The same letters and numbers refer to the same partsin differentfigures.

'0. are the wheels, 27 and 28 the end sills,

b the transoms, c the safety-beams, j the bolster, cl the axles, e the wheels, f the equalizing-bars, s the equalizing-bar springs, S the bolster-springs, h the spring-plank, and g the spring-bar hangers, of a truck.

in are the side sills, m the end sill, and n the intermediate sills, of a car-body.

Each end of a car-body is supported by the bolster of the truck; but the king-bolt is placed at the end of the ear-body and directly over the end pieces of the truck-framing, as shown in Figs. 2 and 3. The parts, in combination with the king-bolt, are attached to and carried by the end sills m of the car-body, as shown in Figs. 2, 8, 4, 5, and 6. Rollers 16, Figs. 2 and 3, are attached to and carried by the bolsterj, and a plate 19, Figs. 2, 3, and 6, is secured to the bottom of the car-body, which rests and rolls upon the rollers. A roller 22 is supported by the inner end of the truck-framing, and a plate 21, Figs. 2 3, and 6, is attached to the bottom of the car-body and rests upon and rolls on the roller 22.

The above description gives a general idea of the essential features of the invention.

The invention will now be described in detail. The truck-framing ends are made of two parallel fiat metal bars 27 and 28, attached at their ends to the ends of the wheelpieces a. The piece 27 is placed exteriorly, and has its ends secured to the ends of the wheel-pieces a by bolts 30. The piece 28 is placed within the piece 27, and has elbows 29 at its ends secured to the insides of the wheel-pieces a by bolts 30. The truck kingbolt plate 2 is supported and held in position by means of transverse links 13, hinged thereto at 4, and to a device between the end pieces 27 and 28 on each side and contiguous to the wheel-pieces a, Figs. 2, 3, 4:, and 5. The device to which the outer ends of the link 13 is connected consists of a thick end part 6, secured to the inside of the wheel-piece a by bolts 30, Figs. 4t and 5, side extensions 7, Figs. 2, 3, 4, and 5, secured to the end pieces 27 and 28, a pin 9, having sliding bearings and a hingeeye ll atits inner end to hinge to the outer end of the link 13, a follower 8, and a spring 10. The parts 6 7 form a box or casing closed at the outer end and on the sides and open at the inner end and at top and bottom and is made to lit the space between the end pieces 27 and 28. The sides 7 have hori-.

zontal central ledges 25, Figs. 1, 5, and 7, which support and guide the follower 8, secured on the pin 9, that has a boss 36 to retain the follower 8 in position. The outer end of the pin 9 slides in a hole in the end part 6, and a hole 34 is made in the wheelpiece a to allow the pin 9 to play freely in its bearings. A spring 10 is placed and held around the pin 9 between the end part 6 and the follower 8.

The truck king-bolt plate 2 has a hemispherical depression 37, concentric with the hole 26 for the king-bolt, into which fits and works the hemispherical projection 38 on the king-bolt plate 20, attached to the end sill m of the car-body. The plate 2 has side lugs 4,

to which the inner. ends of the links 13 are.

connected by means of pins 14, and also a lug 3 on its inner side. A link 15 is hinged to the lug 3 by a pin 14: and to a lug 24 on the casting 23, which is attached to the top side of the adjacent transom b by a pin 14. The

A casting 18, Figs. 2 and 3, having a roller. 16 turning in bearings 17 cast on thepart 18,

is secured on each end of the bolster i by bolts 30.

A circular plate 19, Figs. 2 and 6,is secured to the under side of the car-body by bolts 30;

The plate 19 may be secured to the intermediate sills n by bolts 30, and may be made as shown, or two separate plates may be used,-

one for each roller 16.

Acastin g 32,Fi gs. 1, 2,and 3,has lugs 33,with hinge-eyes, to which links 13 connect by means of pins 14:. The links 13 are hinged at their other ends to pins 9 of the devices above described as being secured between the end pieces 27 and 28, whereby the casting 32 is supported at the inner end of the truck. The casting 32 has bearings 17, in which the pin 14 of the roller 22 turns.

A plate 31, Figs. 1, 2, and 3, is secured to the under side of the car-body by bolts 30, Figs. 1 and 6, and rests on the rollers 22.

Fig. 7 shows an inner end View of the box or casing 6 7, ledges 25, pin 9, and spring 10.

The relative arrangement of the parts of the invention and the mode of operation'can now be explained.

The object of the invention described is to locate the pivotal connections between the trucks and the car-body at points which will cause the least possible sideswing of the car ends when running on curves. By placing the king-bolts at the ends of the car-body-the ends of the car are moved more nearlycoincident with the lateral motions of the end wheels, the ends of the same car are kept more nearly in the line of the track, and the contiguous ends of adjacent cars are held closer together laterally. Such an arrangement and mode of operation enables the cars to run without sudden sidewise end swing, and consequent lateral rotation about the pivotal connections of the car and trucks, and hence conduces to safer, faster, easier, and more comfortable travel.

We claim- 1. The combination of a railway-car body, car-trucks, a pivotal connection between the car-body and the truck located eccentrically of the truck-center toward the adjacent end of the car, and supporting parts for the carbody attached to the truck-bolster and arranged to move freely-laterally under the carbody, substantially as set forth.
